IMPROVEMENT IN WIND-WHEELS.

Specification-forming part of Letters Patent No. 180,679, dated August1, 1876; application filed June 12, 1876.

a; av, Fig. 2. Fig. 2 is a top View ot' the same.

Fig. 3 is av detail cross section ot' one ot' the fans.

Similar letters of reference indicate corresponding parts.

The object ot' this invention is to improvel the construction ot`wind-wheels to enable them to be adjusted, to cause them to work withmore or less power, as may be desired.

The invention consists in the combination of the suspended weights, theadjustable. bars,

and the curved screw-rods, and their nuts, with the radial arms and thefans of a windwheel, as hereinafter fully described.

A is the shaft of the wind-wheel, the ends ot' which, orjonrnalsformedupon or attached to said ends, revolve in bearings in a framework, B. Tothe upper part ot' the shaft A are attached radial arms G, to the outeilparts ot' which the fans D are pivoted, andthe outer ends of which areconnected by bracerods c. To the arms C, above the centers of the fansD, are pivoted the suspended weights E, which hang behind the fans D tohold them against the wind. With the upper ends of the suspended weightsE are connected the upper ends of the bars F, which hang in front ot'the fans D, and are at an angle ot' forty-ti ve degrees, (450,) more orless, with the weights E, as may be desired. To the weights E areattached the ends ot the curved rods G,which pass through the fans D,through the lower ends of the bars F, and have screw-threads cut upontheir projecting ends to receive the nuts g', so that, by adjusting thesaid nuts g, the power of the wheel may be regulated, as

required. Rubber blocks H are attached to the forward sides of theWeights E for the fans D to strike against, to prevent noise.

With this construction, as the wind blows against the forward sides ofthe fans D, it presses them against the weights Fagand the weightssupport them against the wind, unless it be strong enough to raise thesaid weights, and thus take the fans out of the Wind. Upon the otherside of the wheel, where the wind blows against the back ofthe fans, thefans swing up against the arms F before the weights E can oii'er anyresistance, and it" the bars F were at right angles with the weights Ethe fans would rise into a horizontal position without encountering -anyresistance from the weights. It' the bars F were down close t0 theforward side of the fans, the weights E would oft'er the same resistanceto the wind, whether'it blew against the forward or rear sides ot' thefans, and the wheel would stand still, so that, by adjusting the`position ot' the` bars F with the nuts g', the

wheel may be adjusted to work with any de` sired power. f

To the shaft A is attached a wheel, I, atan angle with the said shaft.the rim of' which enters a slot in the end ot' the pivoted lever J, andvibrates the said lever to give motion `t o the machine-to be driven; orpower may be taken from the shaft A by gearing, if desired.

Having thus described my invention, I claim asnew and desire to secureby Letters Patent- The combination ot' the suspended Weights E, theadjustable bars F, and the curved screw-rods Gr, and their nuts g', withthe radial arms C and the fans D of a wind-Wheel, substantially asherein shown and described.
